Evidence is increasing that the integrity of sperm DNA may also be related to implantation failure and recurrent miscarriage (RM). To investigate this, the sperm DNA fragmentation in partners of 35 women with recurrent implantation failure (RIF) following in vitro fertilization, 16 women diagnosed with RM and seven recent fathers (control) were examined. Sperm were examined pre- and post-densit...

In 1978, a new era has started in the treatment of infertility by the birth of the first baby from a pregnancy achieved by in-vitro fertilization. Following this, healthy pregnancies have been achieved by assisted reproductive techniques such as in-vitro fertilization by an important percentage of the childless couples. Despite all developments in assisted reproductive techniques, pregnancy rat...

Objective : To determine whether women with factor V Leiden mutation, a common inherited defect of coagulation, are at increased risk for recurrent pregnancy loss after ICSI. Patients and Methods : Women with recurrent implantation failure were compared to a matching group of women conceived naturally. Factor V Leiden was investigated in each group to determine its homozygosity or heterozygosit...

background: implantation failure is the most important cause of recurrent in vitro fertilization/intra cytoplasmic sperm injection (ivf/icsi) failure. several reports suggest that intercourse during the peritransfer period might improve pregnancy rates. this study is designed to determine whether intercourse during the peritransfer period will improve pregnancy and implantation rates in patient...

Background: The process of implantation involves the interaction of the human embryo and the uterine epithelium. Failure of implantation is a major reason for infertility in women and the inability to achieve endometrial receptivity is responsible for much of the failure of reproductive technologies. Management of repeated implantation failure despite transfer of good-quality embryos still rema...
